External Balancer

External Flange Mounted for Grinding Machines

Fully automatic operation means you no longer need to pre-balance grinding wheels, and eliminates the need for awkward equipment, which only does part of the job. Greatly reducing set-up time and ensuring a smoother running, more efficient grinding operation.

System principles
The system operates on a principle of mass compensation for wheel imbalance. The balance head contains two movable eccentric weights, each weight is driven by electric motors through a precision gear train. These weights can be repositioned to offset any imbalance in a grinding wheel.

Unbalanced balanced
Imbalance or vibration is picked up by the sensor. The signal is fed to the controller, which filters the signal by RPM. The controller then drives the two balance head weights in the direction that reduces the amplitude of the vibration signal. When the weights are positioned so the lowest vibration level is reached, the balance cycle is complete.

System components
Computer Control features a bright graphic display in a sealed enclosure for the harshest of grinding environments. Sensor monitors vibration levels with precision accuracy. It can be mounted with the magnet supplied or the magnet easily un-screws for stud mounting. Balance Head compensates for wheel imbalance. Balance is maintained even if wheel is stopped and re-started. Spindle Adapter attaches balancer head to the grinder. It allows easy removal of the balance head for quick wheel changes.
